Support for undiagnosed conditions

Sometimes professionals are unable to diagnose a child. This may be because your child: 

  • has a rare condition  
  • experiences features or symptoms linked to many conditions, making it difficult to make the correct diagnosis 
  • has symptoms that become more noticeable as they get older, leading to a late diagnosis 

If you are not able to receive a diagnosis for your child, you, your family and child will still be entitled to support.

Support should be based around the needs of the child; therefore, it is essential to collect evidence of their needs so that the right support can be put in place as early as possible. 

Seeking advice or referral for assessment

If you are a parent concerned about your child’s development you should speak to your GP, health visitor, school health nurse, social worker or early help coordinator, depending on who currently works with your child.  

If the concerns are severe or ongoing and you would like your child to be assessed for complex disabilities, you should see your GP. They can refer you to a Community Paediatrician to seek a potential diagnosis and to access specialist support.
